What image formats does GPT Image 1 support?

Confirm the current supported input and output image formats in the model documentation. Test with your specific image requirements.

How much does GPT Image 1 cost?

Check the current pricing page for per-image costs. Consider GPT Image 2 for improved quality and efficiency.

How should you set the output budget for gpt-image-1?

For gpt-image-1, set the max_tokens or max_completion_tokens parameter to control spending per call. Start with a budget aligned to your typical response length and increase only when longer outputs are genuinely needed. Monitor token usage in the API response headers to tune your budget over time.

Can you call GPT-Image-1 with the OpenAI SDK you already use?

Yes. GPT-Image-1 is reachable through an OpenAI-compatible endpoint, so an existing OpenAI SDK client works after pointing the base URL at MixRoute and setting the model parameter to gpt-image-1 . Keep your current request and response handling.

How much does the price differ by resolution on gpt-image-1?

gpt-image-1 prices output by image size or quality. The listed rows are 40.00 USD per 1,000,000 tokens (Image tokens); 20.00 USD per 1,000,000 tokens (Image tokens).

Does GPT-Image-1 support editing an existing image?

Yes. GPT-Image-1 exposes an image editing endpoint, so existing images can be edited rather than only generated.

How many images can GPT-Image-1 generate per request?

GPT-Image-1 returns up to 10 images per request.

What should you check before using it?

Confirm output sizes and supported image formats

GPT-Image-1 supports streaming, prompt caching, vision input and the OpenAI SDK. Released 2025-04-23. It is billed at 10.00 USD per 1M tokens. Test a representative workload before production.

Why use it through MixRoute?

Swap the base URL, keep the GPT-Image-1 client

MixRoute serves GPT-Image-1 on the OpenAI-compatible endpoint /v1/chat/completions; point your existing client at https://api.mixroute.ai/v1 with the model ID gpt-image-1 and re-run your integration tests.

Capabilities & compatibility

Unconfirmed capabilities stay "Unknown," no guesses

Streaming

GPT-Image-1 supports streamed responses.

EX stream: true streams tokens incrementally, so chat UIs render as they arrive.

Prompt caching

GPT-Image-1 supports prompt caching under supported routing conditions.

EX Keep the system prompt and tool definitions at the start of the request; repeated prefixes are automatically billed at the cache-read rate.

Vision input

GPT-Image-1 can process image inputs alongside text.

EX Pass a base64-encoded image in a image_url content part alongside text messages.

OpenAI SDK

Call GPT-Image-1 through MixRoute's OpenAI-compatible endpoint.

EX Change base_url to https://api.mixroute.ai/v1; everything else follows the OpenAI style.
